I've been keeping an eye on the UL30JT too (at least since someone recommended it to me over on Notebookforums yesterday)
I'm in the market for an ultra-portable with workstation specs and it looks like there aren't too many options.
I'm trying to keep it below 14" (perfectly fine with 12-13" screens) and would really like to keep the weight down around 4lbs or less. My current Thinkpad X60 tablet is 4.7lbs and biking back and forth to work every day makes me wish I had something a bit lighter. I need something with good specs too - lots of number crunching and other cycle-intensive applications. For that reason, I want to get something in either the i5 or i7 range with DDR3 and a good (read: Intel) SSD. Battery life is not too much of a concern, so no need to worry about the LM or UM processors.
Right now the new Thinkpad x201 is at the top of the list since its the only i7 machine with the size/weight profile I can find (12" screen, 2.5lbs! - its like a Netbook with real guts (and a real pricetag!). I'm not too keen on getting one of the Samsung SSDs that Lenovo is shipping with the machines, though.
The UL30JT seems like it might just be small enough to seriously consider. The new Alienware M11x looks great, but I'm concerned that the processor is pretty underpowered compared to the i7s in the Thinkpad. (Even OCing it to 1.73, I wonder how it stands up to the i7 line?)
Anyone know of any other builds that fit the profile I describe?
Price wise - the $1000 tag on the ASUS is certainly more desirable than the $1500 for the Thinkpad, but I'm willing to go up that high.
